Stubborn heat wave triggers another statewide Flex Alert; conservation critical!
 
August 13, 2012 (Folsom, Calif.)  --  The week-long heat wave in California is picking up steam again and the mercury on the rise. A Flex Alert is in effect tomorrow and consumers are urged to reduce their energy use.

The ISO thanks consumers for their tremendous conservation efforts during last Friday’s Flex Alert.  Nearly 1,000 megawatts in energy reduction helped maintain grid reliability. The level of conservation is equal to the output of two large power plants.
 
The main grid operator for California asks consumers to repeat efforts. Find Flex Alert tips at www.caiso.com.
